Alrighty, finally got to this one.
I'll type what I think as I listen...
I actually like the acoustic sound and lead tone for the intro.
The drums in the intro around 1:00 sound too distant to me.
Nice electric tones at 1:45. TIght playing!
Hey cool, the song has vocals... I wasn't expecting that after listening for this long. Sounds good.
Love the little acoustic breaks, nice sounds there. Those thinner more distant drums on those parts are starting to grow on me. Maybe it's just the intro that could use some more beef. Good guitar work around 5:00... love how the song seems to build slowly from that point on.
The mood switch at 6:45 is cool, but there's something about the vocals that just doesn't sit right to me.
The rest of the song is excellent. Sounds really intense. Hey, it's only 9:30, false advertising

... actually I think you should extend that acoustic ending a bit more, sounds like it ends too abrupt in my opinion.
Overall, excellent work! Really enjoyed the song
